not for mainstream applications?
So all of the HDS VSP customers etc are running nothing but things like hadoop on their storage systems?
Makes no sense to me.
None of my VM hosts have storage at all, they even boot from SAN.
I would think in most cases things like Hadoop would be using local storage, I'm not in the hadoop realm but have only personally head of one company that used network storage for hadoop over the years(ironically enough it was HDS storage, with BlueArc I think).
